Initial tweet valence, abuse volume, and observer Dark Tetrad characteristics influence perceptions of female celebrity abuse on Twitter

Research into relationships between victim-generated content, abuse received, and observer characteristics when considering Twitter abuse has been limited to male victims. We evaluated participant perceptions of female celebrity victims and abuse received on Twitter. We used a 3 (Initial Tweet Valence; negative, neutral, positive) × 2 (Abuse Volume; low, high) repeated measures design and online survey method. Participants were shown tweets generated by six female celebrities, counterbalanced such that each participant saw each celebrity in one Valence-Volume condition. Stimuli were presented across six ‘lists’ such that celebrity ‘victims’ could be rotated across Valence-Volume pairings. Participants rated—per target stimulus—the level of blame attributable to the victim and the perceived severity of the incident. Furthermore, participants were asked to complete a Dark Tetrad scale—measuring their Machiavellianism, Narcissism, Psychopathy, and Sadism. Analyses determined that victim-blaming was influenced by victim Initial Tweet Valence (greater victim-blaming associated with more-negative content) and observer Machiavellianism. Perceived severity was influenced by victim Initial Tweet Valence, Volume of Abuse received, and observer Machiavellianism. Results were consistent with previous research involving male celebrity victims. Further research is needed to understand the contributions of participants’ hostile and benevolent sexism, as well as the role of victim attractiveness.

Victims are often blamed for acts perpetrated against them 1 .Two explanations for this are Just World Theory 2 and Defensive Attribution 3 .Just World Theory suggests that people believe the world to be a just and fair place in which people 'get what they deserve' .Thus, if harm is visited upon an individual then they must be deserving of it in some way.Defensive Attribution posits that individuals attempt to increase their sense of control by attributing harm that befalls others to the disposition of those individuals rather than to the environment they inhabit.Both defensive cognitions are designed to make individuals feel safe-victims of abusive acts brought harm upon themselves.
Victims of cyberabuse are often blamed for the abuse they receive 4 .Sympathy and support from family, friends, and authorities is often lacking 5,6 .Public perception is typically that online abuse is less harmful than offline abuse 7 .Often, the opposite is true 8 .Whereas offline abuse is sometimes fleeting and can perhaps be escaped from, abusive messages online are potentially permanent and can be shared with multiple audiences.It is hard for victims to escape negative content in online spaces without isolating themselves 9 .
Women receive proportionally more online abuse than men 10 .Women are vulnerable to image-based sexual abuse 11 .Women who express views about feminism and women's rights are often targeted 12 .Compared to abuse directed to men, abuse against women on Twitter (now X; we use Twitter as this was current when our data was collected and is consistent with previous relevant literature) is likely to be sexist or misogynistic, and contain

The Dark Tetrad
The Dark Tetrad of personality (DT), reflecting subclinical variants of Machiavellianism, narcissism, psychopathy, and sadism 28 , has been implicated in both perpetration of online abuse and abuse perceptions.Psychopathy and sadism predict cyber-aggression perpetration, mediated predominantly by moral disengagement 29 .Machiavellianism, psychopathy, and sadism have been linked to enjoyment of online trolling behaviour and personal identification with trolls 30 .
Observer Machiavellianism, narcissism, and psychopathy predicted decreased perceived severity of abuse for both male celebrities and non-celebrity males on Twitter, while those high in narcissism and sadism demonstrate a higher propensity for victim-blaming 25,26 .Hand and Scott 27 found that victim blame was predicted by observer Machiavellianism and psychopathy and that perceived severity was predicted by observer Machiavellianism.However, no research has yet examined observer DT traits in attitudes towards female victims of online abuse.DT traits and unsympathetic attitudes towards victims are argued to be underpinned by propensity towards sexist ideology 31 .Males and females who demonstrate high levels of DT traits exhibit elevated hostile and benevolent sexism 32 .Accordingly, the tendency to victim-blame and downplay perceived severity may be heightened in those with stronger DT characteristics.

The current study
Participants processed six Twitter threads consisting of an initial tweet by a female celebrity followed by six replies.Initial tweets were either negative, neutral, or positive in valence.Replies included two (low volume) or four (high volume) abusive comments out of six.Participants indicated victim-blaming and perceived severity per target.Finally, participants completed a DT questionnaire.
Specifically, we predicted that a negative initial tweet would be associated with greater levels of victim-blaming.Female celebrities who tweeted negative content would be blamed more than celebrities who tweeted neutral or positive content.Related to this, we predicted that Tweet valence would impact perceived severity of subsequent abuse; abuse following negative initial tweets would be perceived as least severe.Abuse received by female celebrities who post negative content would be viewed by observers as less severe than 'unprovoked' abuse following neutral or positive content.Furthermore, we predicted that A higher volume of abuse would be associated with greater perceived severity.The more abuse female celebrities received, the more severe an incident would be perceived to be.Considering DT characteristics, we predicted that there would be positive associations between participants' DT scores and attributed victim blame and there would be negative associations between participants' DT scores and perceived severity.Participants scoring high on DT personality traits would generally demonstrate less empathy than others.Accordingly, they would minimize the harm and discomfort they perceive others to experience, while maximizing their defensive attributions.

Data analysis
There were no missing values across profile ratings or DT measures.Two 3 (Initial Tweet Valence: negative, neutral, positive) × 2 (Abuse Volume: low, high) repeated measures analyses of variance (ANOVAs) were performed on victim blame and perceived severity ratings.Multiple linear regressions (stepwise method) explored predictors of victim-blaming and perceived severity-note.prior to this, Pearson's correlations (one-tailed) identified relationships between co-variates and determined candidates for regression analyses.

ANOVAs
Descriptive statistics for victim blame and perceived severity across conditions are presented in Table 1.
The main effect of abuse volume on victim blame was non-significant [F(1,392) = 1.66, p = 0.200].
The main effect of abuse volume on perceived severity was significant [F(1,392) = 247.85,p < 0.001, η p 2 = 0.558].Perceived severity was greater following a high volume of abuse (3.87) than a low volume of abuse (3.14).
The assumption of sphericity was upheld for the initial tweet valence × abuse volume interaction (W = 0.998, p = 0.860).This interaction was non-significant [F < 1].

Regressions
Correlations between covariates which reached p < 0.10 were considered as candidates for multivariate models (as in Hand et al. 25 ; Scott et al. 26 ); typical significance limits (p ≤ 0.05) may fail to establish significance in dimensions otherwise known to be predictive 33 .Underlying correlations are summarised in Supplementary Materials II.Multicollinearity, independence of error terms, non-zero variances, normality, homoscedasticity, and linearity assumptions were upheld.Stepwise regressions were conducted for both victim-blaming and perceived severity.
As victims' tweets shift from negative to neutral, victim-blaming is significantly reduced; in turn, as initial tweet valence shifts from neutral to positive, again, victim-blaming is significantly reduced.Machiavellianism influences victim-blaming-participants who score more highly on this dimension attribute greater victim blame.A nuanced picture of perceived severity is presented.The volume of abuse received is particularly important in influencing ratings of perceived severity.As participants' initial tweets move from negative to neutral, perceived severity increases, and as initial tweets move from neutral to positive, again there is an increase in perceived severity.As observer Machiavellianism increased, perceived severity typically decreased.

Discussion
Our findings broadly supported all hypotheses.A complex interplay between victim-generated content (i.e., initial tweet valence), user-generated content (i.e., abuse volume), and observer characteristics (especiallyespecially Machiavellianism) shape perceptions of Twitter abuse involving female celebrities.This demonstrates both top-down (i.e., internalised) and up-bottom (i.e., stimulus-driven) risk factors in observer assessments of online abuse.

Tweet valence and abuse volume
Victim-blaming was greatest when initial tweet valence was negative, supporting our hypothesis.According to Warranting Theory 23 a tweet is a salient identity claim.There was no difference between victim-blaming across neutral vs. positive tweets, in line with Hand et al. 25 who studied male lay-person victims.Observers attribute victims blame due to self-serving defensive attributions 3 .Our findings demonstrate that observers attribute more victim blame when they believe users have provoked abuse-tweeting abusive or negative content 26 .However, the current pattern of contrasts across levels of Initial Tweet Valence are somewhat different than those of Scott et al. 26 (male celebrity victims) and Hand and Scott 27 (male celebrities, male lay-persons), who found significant differences between all three levels of Initial Tweet Valence.These cross-study differences can be explained by a 'crash' in victim-blaming of female celebrities when tweets are anything-but-negative.With male victims (particularly male celebrities), previous victim-blaming data has shown a staggered, step-down across levels of initial tweet valence.This demonstrates a difference in how men and women are viewed online and merits further exploration.
Initial tweet valence impacted perceived severity.Perceived severity was lower in relation to negative than either neutral or positive initial tweets; there was no neutral vs. positive tweet perceived severity difference.These results support our hypothesis and dovetail with those involving male celebrities 26,27 .However, present results contradict Hand et al. 25 who found no effect of Initial Tweet Valence on perceived severity for male lay-person victims.There appears to be something 'special' about celebrities-regardless of sex-and the victim-generated content and perceived severity association.Observers understand that celebrities' use of social media may be more self-serving than lay-users' .Features of the online environment allow users to manage their personas more-carefully than in off-line situations (per the Hyperpersonal Model 34,35 ); they can do this via identity claims.Consequently, not only may celebrities be blamed more for abuse received, but incident perceived severity might be lower 26,27 .
We predicted that a higher abuse volume would be associated with greater perceived severity, and this was supported.This aligns with previous studies involving male victims (celebrities, laypeople [25][26][27] ).Behavioural residue is traditionally considered to be more accurate than identity claims, holding more weight in online impression formation (per Warranting Theory 23,24 ).In this context, it contributes to observer impression formation and demonstrated that participants are not indifferent to abusive content and are capable of simultaneously recognising severity whilst also attributing victim blame.Results are consistent across victim sexes and status,

Observer Dark Tetrad
Positive associations between participants' DT scores and victim-blaming were found, as hypothesised.When Initial Tweet Valence was neutral or positive, there were significant positive associations between all four DT dimensions and victim-blaming.When Initial Tweet Valence was negative, there was a negative relationship between observer Psychopathy and victim-blaming-as in Hand et al. 25 .It may be that observers with high psychopathy rather than identify with abusers instead 'see themselves' in the victim who has tweeted the negative content, and therefore attribute less blame because of defensive attributions 3 .It could also be that due to the lack of empathy that typifies individuals with higher psychopathy, they view the abusive tweet as acceptable and therefore deem the abusive reactions uncalled for.Regression analysis on victim blame data revealed that user-generated content (i.e., Initial Tweet Valence) was the largest contributor in explaining victim blame variability; Machiavellianism also contributed to the model.As observers' Machiavellianism increased, as did their likelihood of attributing victim blame.This is in line with Hand and Scott 27 .However, unlike previous research investigating perceptions of male victims, there was no place in the regression model of victim blame for narcissism (per Scott et al. 26 ), sadism (per Hand et al. 25 ), or psychopathy (per Hand and Scott 27 ).These contrasting model structures suggest that there is a different interplay between victim-generated content and observer DT characteristics when victims are female as opposed to male.
Considering associations between observer DT scores and perceived severity, evidence was mixed, partially supporting our hypothesis.There was no evidence of a linear relationship between perceived severity and observer narcissism or sadism (n.b., this is consistent with certain results of Scott et al. 26 [their Table 3], Hand et al. 25 [their Table 4].There was mixed evidence for a relationship between observer Machiavellianism and psychopathy on perceived severity; this depended on victim initial tweet valence.Regression analysis of perceived severity data revealed that abuse volume and initial tweet valence explained larger proportions of variability than observer characteristics; however, observer Machiavellianism significantly contributed to this model.This is in-part consistent with Hand et al. 25 and Hand and Scott 27 .Unlike previous research investigating perceptions of male victims, models of perceived severity did not include narcissism (unlike Scott et al. 26 ) or psychopathy (unlike Hand and Scott 27 ; Hand et al. 25 ; Scott et al. 26 ).However, this does somewhat align with Lyons et al. 36 who found that, of the three DT traits, those high in Machiavellianism alone were unable to correctly identify high-risk scenarios where females were likely to be sexually victimised.This suggests that those high in Machiavellianism fail to grasp the risk that online abuse may pose to female victims.
The current study used the 9-item Assessment of Sadistic Personality (ASP) tool 37 .These items were also used in similar research 25 .The 9 ASP items align with three theoretical origins-subjugation, pleasure-seeking, and non-empathy.However, other studies 38,39 have utilised the 18-item Comprehensive Assessment of Sadistic Tendencies (CAST 40 ).The CAST provides an overarching sadism score across three dimensions-verbal sadism, physical sadism, and vicarious sadism.Future research into the factors relevant in the current study may benefit from using the CAST to facilitate a more nuanced exploration of the independent and combined contributions of verbal, physical, and vicarious sadism.

Implications for female users
Gender, and the assumptions that individuals hold about gender roles, may provide a particularly salient cue to individuals forming impressions in the relatively impoverished online environment (Social Identity Model 41,42 ).When individuals behave outwith gender-sex roles expectancies they are often judged harshly and viewed as less competent by others 43 .This has been shown in online abuse towards female journalists 44,45 .By posting negative comments, female users could be perceived to have traversed the expected bounds of their gender-sex role and are therefore culpable for subsequently received abuse.More research is required to investigate this further.
Due to a general bias towards negative stimuli, viewers may attend to negative comments (abuse) more than positive comments 46 .In the context of online gender-sex role cues, online abuse may represent a social sanction against women 42 .This is relevant to the current study as even though exchanges containing a high volume of abuse were perceived to be more-severe, this does not necessarily mean that victims were believed to be undeserving of abuse.
Another salient cue is attractiveness, most obviously conveyed on social media via profile pictures (as well as conveying gender-sex).The current study neither manipulated the attractiveness of female celebrity victims, nor asked experimental participants about perceptions of victim attractiveness.However, data obtained from naïve participants during stimulus creation and norming suggests that our female celebrity 'victims' edged towards the positive (i.e., 'attractive') end of familiarity and feelings dimensions.Hand and Scott 27 found that male celebrities were more socially-, physically-, and task-attractive than male laypersons, and that these attractiveness-es influenced victim-blaming and perceived severity.It may be that female celebrity victims were 'attractive' to participants, and this may have driven, for example, the 'crash' in victim-blaming when initial tweet valences were non-negative.Future research should explore the impact of victim attractiveness in relation to cyberabuse incidents involving female celebrities and female lay-persons, using carefully controlled stimuli.

Limitations
One potential limitation of the current study was the sample composition-mainly younger adults and mostly women (our sub-sample of 32 men may not be representative of the broader population).Evidence suggests that males and females differ in DT characteristics.For example, psychopathy has been diagnosed more-frequently among males; in a forensic sample, 15-30% of males a diagnosis of psychopathy, compared to between Vol:.( 1234567890 47 .Males generally score significantly higher in narcissism 48 .Machiavellianism is typically found to be higher among males 49 .The authors conducted analyses based on 'gender' with the current data set (we asked participants for their gender, rather than biological sex), and found no compelling evidence of independent effects nor interactions with other co-variates.Future research should carefully unpick contributions of participant sex and/or gender when considering perceptions of cyberabusive incidents and victims.
Replicating this work with a large, diverse, and representative sample is important to enhance the generalisability of the current findings.For example, ensuring appropriate representation of younger adults, middle aged, and older adults.It would be interesting to revisit the current issues with an adolescent population; however, this would present legal and ethical challenges, particularly given the provocative language necessary within the tweet stimuli.Ensuring representation of participants from across geographic and socio-economic diversities would strengthen work in this field, with a view to moving away from predominantly WEIRD representation.
We are confident that our tweet stimuli-which have been extensively normed as part of other projects 26 -are valid and realistic.However, it is a potential limitation of the work that participants were not looking at 'real' tweets inside Twitter itself.This may hinder the ecological validity of the study; however, it is a difficult balance to trade off the validity of interacting with dynamic stimuli in-app or on-site vs. the experimental control and rigour of off-line, carefully controlled stimuli.

Conclusion
The current study is, to our knowledge, the first to examine the online abuse of female celebrities in this way.We found that female celebrities were only victim-blamed following negative initial tweets.Incidents were perceived to be severe unless initial tweets were negative.Observer Machiavellianism contributed to perceptions of both victim blame and perceived severity.
Although generally following the pattern of previous results investigating perceptions of abuse against male celebrities and male lay-users [25][26][27] , we identified subtle differences in observer impressions of abuse against female celebrities.Some of these can be explained by celebrities being viewed differently to lay-users and being viewed as more culpable for abuse they receive.Gender-sex differences may be explained by online perceptions of gender-sex roles and may be linked to victim attractiveness and observer benevolent sexism-more research is needed to explore this.Further research is required-working with victims, perpetrator, observers, technologists, legislators, etc.-to develop practical interventions to reduce offensive behaviour, encourage prosocial behaviour, and ensure that victims are supported appropriately.

Method Participants
An a priori power analysis (G*Power 3.1.9.2) was conducted [F-test family, α = 0.05, desired power = 0.95 50 , smallest anticipated effect size = 0.15 (based on Scott et al. 26 ].Estimated target sample size was 150.Eventually, 197 participants completed all components of the study (164 women, 32 men, 1 non-binary participant; M age = 30.01years, SD age = 7.96; range 18-68 years; median = 28 years; mode = 24 years).Participants were recruited through opportunity sampling entirely online between December 2020 and February 2021.Recruitment took place via advertisements on the researchers' social media networks.Inclusion criteria included: native or proficient speakers of English (for non-native speakers, at least high school proficiency or equivalent) with no diagnosed visual impairments.Explicit exclusion criteria prohibited individuals under the age of 18 from taking part.

Design and materials
We employed a quasi-experimental 3 (Initial Tweet Valence: negative, neutral, positive) × 2 (Abuse Volume: low, high) repeated measures design and an online survey method to explore participants perception of victim blame and perceived severity.Participants' DT scores were recorded and associated with victim-blaming and perceived severity.
We created original victim profiles.To determine the names of the six female celebrity victims, we first established a 'long list' of 30 prominent female celebrities (actors, presenters, performing artists, sportspersons).The names of these celebrities were provided to an independent group of 27 participants who were asked to rate each for their familiarity (1 = not at all familiar, 5 = extremely familiar) and feelings associated with the named individuals (1 = very negative, 5 = very positive).We subsequently extracted six target celebrities (all active Twitter users in real-life) who were perceived as relatively neutral in terms of familiarity (each celebrity's mean familiarity rating lay between 3.63 and 3.74; aggregated mean familiarity = 3.70, SD = 0.04) and feelings (each celebrity's mean feeling rating lay between 3.44 and 3.85; aggregated mean feeling = 3.73, SD = 0.15).The six celebrity 'victims' extracted were Zoe Ball, Fern Britton, Tess Daly, Joanna Lumley, Jennifer Saunders, and Denise Van Outen.
Multiple sets of stimuli were created so that every celebrity victim was seen in each of the initial tweet valence × abuse volume conditions.These lists were counterbalanced and rotated such that each participant saw each victim only once yet saw a stimulus in each tweet valence × abuse volume condition.
Each participant saw six target stimuli, composed of an initial tweet by a female celebrity profile owner followed by six replies from Twitter users unknown to the participants.Stimuli were created using Microsoft Paint.Each stimulus consisted of (in order): celebrity 'victim' name and profile picture; their initial tweet; the number of comments, retweets, and favourites (numbers of which were controlled); then finally the six replies.Victims' initial tweets were either negative, neutral, or positive, and within the six replies, either two (low volume) or four (high volume) were abusive.The written tweet content and replies (neutral and abusive) were identical to those of Hand et al. 25 and Scott et al. 26 .An example stimulus is presented in Supplementary Materials I. Full details of the norming procedures for these tweets and replies are provided in Scott et al. 26 .Example tweets included:
